Rearrangement of 2-hetarylalkylpyridinium salts

The rearrangement of 2-thienyl- and 2-furylalkylpyridinium salts to the corresponding anilines by the action of methylammonium sulfites has been studied. It has been shown that the rearrangement of these salts is accompanied in many cases by the formation of phenols and dealkylation products. The influence of the length of the alkyl chain between the heterocyclic rings on the ratio of the rearrangement products has been investigated.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 3, pp. 368–371, March, 1986.
